The posts by Dan and others have been insulting in tone and substance all along. Towards myself and others. They generally don't even have the respect to address senior instructors, Doshu, or O'Sensei with their rightful titles. I responded in kind.

If you're going to get prickly about titles, you should know that O Sensei has no apostrophe. O is an honorific meaning "Great," not the signifier for a Celtic family relationship.
